Electronic – Circuit Protection


I want something for my power that acts like a diode, but without the voltage drop, to protect the circuit from damage if the batteries are connected the wrong way. Is this even possible?

Best Answer

Put the diode across the supply connections so that it is non-conducting, with a fuse ahead of it. The diode will conduct if the supply is reversed, and blow the fuse. There won't be any voltage drop.
